MACHINE FOR STRIPING PAILS, TUBS,

SPECIFICATION forming part of Letters lPatent No.'290,329, dated December 18, 1883. Application fil er 1 October 18,1883. (No modelf) To all whom it may concern: Be it known that I, CHARLES HOFFMANN, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Machines for Striping Pails, Tubs, &e.; and I do hereby' declare that the following is a full, clear, and exact description thereof. f My invention relates to pail-stripers, and will be fully described hereinafter. In the drawings, Figure 1 is a vertical section of my improved pail-striper through its: center. Fig. 2 is a vertical section of same on line 3 y of Fig. 1; and Fig. 3 is a top view of one of the striper-disks. 1

A is the frame, to the rear cross-pieces, A A, of which are bolted the standards B B. A flanged block, 0, is adapted to slide down be-' tween said standards B B, as a pedal-lever, I), connected to said block by rod E, is depressed by the foot of the operator.

F is a weight put on end of i said lever D to keep said block 0 up in itspositionto receivethe pail H. Said block 0 carries a bearing-box, a, for the spindle b of a chuck, G, made of a form} and size to almost fill said pail H, which is maintained in its place on said chuck G by means of cushions c c c, of any suitable elastic. material, partly embedded in slots formed in the periphery of saidchuck,-but proj ecting enough out to sufficiently press against the inside faceof the pail-staves. Said chuck G is held in said bearing-box a on block 0 in a downward inclined position to match with the sloping surface of said pail H, so that its hoops c e 0 may present their face in a line parallel to the rim of the striper-disks R R on shaft I. On top front rail of said frame A is fastened a bracket, J, which has a bearing for the spindle-shaft k, free to revolve in same on the line of and true with said chuck G. Said spindle is is provided with a cap, z, on its inside end, and between said cap 41 and the bearing-bracket J is mounted a coil-spring, Z, designed to press said cap 1' against the bottom of the pail after the bottom edge, 1', of said pail has depressed said spring Z as it slipped over the sloping face of said cap *5.

L is the paint-pot, the bottom of which forms two troughs, M M. Bearing-studs n a and stuffing-bores n n are formed in the ends of which are rotated'by means of pinions p p, keyed on their front ends. 'Saidpinions'p p said troughs for shafts N N, along-which are 7 fastened the paint-stirring arms 0 0 0 0-0, and

mesh with a cogged wheel, p, that is keyed on shaft 10 of feed-roller I. Said shaft 12 being held in bearing-stud n' and' stuffing-box ar formed in ends of said paint-pot L, is revolved either by a pulley or by the hand-crank Q.

R ER are thestriper-disks, made of any suitable elastic material and freely mounted on shaft I, which is supported in openbearing-studs s s in the end edge of said paint-pot L. They are revolved by the feed-roller P, from which they take the paint. Their-motion is in turn imparted to the pail H, along the hoops e e e e of which they are guided by two'beveledrseparable disks, it, mounted on the clamping ends roof the flat levers T T, said -le'vers T T being fulcrumed on the striper-shaft *I on each side of the striping-disks -R B, and their rear ends closing face to face in a slotted weight, S. The pin r, upon which saidbeveveled disks t t revolve, is long enough to allow of said disks t t following the edges of the hoops e e e, whatever may be the'width of said hoops, the same being thereto adjusted by the screw :0. a ,In' bracket .2, inside of the paint-pot L,-is

hinged the paint-scraper V, the slightly-curved edge of which may be made to press more or I less on the surface of the feed-roller P, as a weight, 0, is placed nearer to or farther from said roller.

U is a chamber, in which a coil of pipe, 1%, circulates steam, hot air, or water, to keep the paint of the requisite limpidity in cold weather.

As may be easily understood from the above description, the pail H being pushed over the cushioned chuck G, the weighted lever D is depressed and brings down the chuck-bearing block 0, when the pail H rests with its hoops e e e on the striping-disks R R B; As the feed-roller P is revolved the paint is transferred from its scraped surface to the rim of the elastic stripers R It R, which transmits said paint to the hoops e e e as the friction of said disks revolves the pail with the chuck G against the back rest spindle, la. The beveled rim of the guide-rollers t t being pressed up against the edges of the pail-hoops e e by the weight S on the rear end of the flexible levers T T, will naturally keep the striping-disks R R in true line with said hoops. For wider hoops than are commonly used 011 pails, a few turns of the screw as will allow of the side-play of said flexible levers T T, and of the adjustment of said guide-rollers t t to the width of said hoops. The striping-disks R R maybe taken off from the paint-pot L and replaced therein by a suitable roller, whereby the paint may be applied in same manner to the staves of the pail, if the quantity of such work does not warrant the use of more than one single machine. Otherwise, the striping of the hoops could be made on one machine, and the painting of the stave on another, my invention applying to both operations equally well.

It must be understood, also, that I do not confine myself to the special form described above. Said form can be varied according to the form, size, and material of the articles to be striped and painted besides pails'such as kegs, barrels, tubs, jars, cans, and generally all vessels of cylindrical form on which paint has to be applied.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A pail-striper having a vertically-sliding block to bear a cushioned chuck, which, by

means of a weighted foot-lever connected to said bearing-block, is adapted to bring the hoops of a pail set over said chuck in parallel contact with the rim of elastic stripingdisks that are fed with paint, as they are revolved, by a feed-roller rotated in a paint-pot, whereby said pail-hoops are painted as the pail revolves with said disks, substantially as set forth.

2. In a pail-striper, the cushioned chuck G on sliding block 0, with inclined bearing a, adapted to bring the sloping staves of a pail in parallel contact with the rim of the stripers, substantially as set forth.

3. In a pail striper, the spindle-shaft is, mounted on bracket J, and having cap i and coil-spring Z, in combination with chuck Gr, substantially as shown and described, and for the purpose set forth.

4. In a pail-striper, standards B B, flanged sliding block 0, rod E, and weighted foot-lever D, in combination with the pail-bearing chuck G, substantially as shown and described, and for the purpose set forth.

5. In a pail-striper, the elasticstriping-disks R R R, mounted on shaft I, in combination with levers T T, guide-rollers t t, weight S, and adjusting-screw ac, substantially as shown and described, and for the purpose set forth.

6. In a pail-striper, the feed-roller P, shaft 19, cogged wheel 19, and crank Q, in combination with striping-disks R R B, substantially as shown and described, and for the purpose set forth.

7. In a pail-striper, the paint-pot L, having troughs M M, bearing-studs n, and stuffingboxes n, in combination with paint-agitating arms 0 0 0 0 on shafts N N, and pinions p 19, substantially as shown and described, and for the purpose set forth.

8. In a pail-striper, the paint-scraper V, hinged on bracket z of paint-pot L, and having an adjustable weight, '0, in combination with the feed-roller P, substantially as shown and described, and for the purpose set forth.

9. In a pail-striper, the chamber U, under paint-pot L, in combination with the coil-pipe 11, substantially as shown and described, and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of \Viscousin, in the presence of two witnesses.

CHARLES HOFFMANN.
